[U-Boot] [PATCH v4 0/4] drivers: Add reset ctrl to drivers

[Ley Foon Tan]

Add reset ctrl to dwmmc socfpga, designware Ethernet and ns16550 serial drivers.

A reset property is an optional feature, so only print out a warning and
do not fail if a reset property is not present.
    
If a reset property is discovered, then use it to deassert, thus bringing the
IP out of reset.

v4 change:
- Add patch to check CONFIG_SPL_RESET_SUPPORT in reset.h
